ANU-ANTIGUA

Antigua is situated at the northern end of what Genoways termed the Lesser Antillean Faunal Core. However, the paucity of chiropteran taxa on ANU (absence of A. nichollsi, E. guadeloupensis) distinguish ANU from neighboring Guadeloupe. Fruit bat captures per net-night (BNN) range from 6.65-2.59 in the neotropics. Phyllostomid captures on ANU are on the very low end of this scale at 1.92 BNN. It seems that ANU's flat terrain, abundant desert scrub, and anthropogenic disturbance during colonial times provide neither the altitudinal gradient to generate rainfall, nor heavily forested valleys whose native fruits might support additional species of fruit bats as they do on the adjacent islands

NEV-NEVIS

Only one species of bat, Molossus molossus, previously has been documented as occurring on the northern Lesser Antillean island of Nevis. Species-area and species-elevation analyses for the chiropteran fauna of the Greater and Lesser Antillean islands gave r2 -values of 0.74 and 0.33, respectively. In the species-area analysis the bat fauna of Nevis falls above the regression line and in the species-elevation analysis it falls almost on the line. Fruit bat captures per net-night on Nevis was 1.69, which is far below other Neotropical areas. This indicates that although the species diversity of bats on Nevis matches other Lesser Antillean islands, the bat population on the island may be below those on other islands.

SKB-ST. KITTS

Despite numerous small unpublished collections of bats from the island of St. Kitts, only two formal surveys (Morton & Courts, 1999; Pedersen, Genoways, & Kwiecinski, 2001) have been conducted on this fauna. These independent efforts covered a broad spectrum of approaches ranging from mist-netting in a variety of foraging habitats to extensive surveys of natural and anthropogenic roost sites. Both surveys produced additional species records for the island and identified major roosting sites that would benefit from local conservation efforts.

Species (7): Seven species of bat are currently reported from St. Kitts: N. leporinus, M. plethodon, A. jamaicensis, A. nichollsi, B. cavernarum, M. molossus, and T. brasiliensis.

SAB-SABA

Our analysis of species/area relationships for West Indian bats provides a slope value of z = 0.177 and R2 = 0.76; therefore, the bat fauna of the West Indies has the flattest slope for this relationship of any West Indian group. This relationship is best explained by a propensity for over water dispersal by West Indian bats. We propose to unite the chiropteran faunas of the islands of ANG, ANU, BBQ, NEV, SAB, SBA, EUX, SKB, and SXM by recognizing them as the Northern Antillean Faunal Area. Given the small size of Saba (12 km2), conservation concerns are expressed for the future of the fauna and some recommendations are made for its preservation.

ANG-Anguilla

Based on data from this study, the conclusion is drawn that the Anegada Passage has had only a limited impact as a zoogeographic barrier for the chiropteran faunas of the Greater and Lesser Antilles, if a perspective of the last 10,000 years is taken.

Species (6): Six species of bats are known from Anguilla—Monophyllus plethodon, Brachyphylla cavernarum, Artibeus jamaicensis, Natalus stramineus, and Molossus molossus, and Tadarida brasiliensis.

SXM-ST. MAARTEN / MARTIN

Species (8): Eight species of bats are now reported from the Antillean island of Saint Martin/Sint Maarten—Artibeus jamaicensis, Brachyphylla cavernarum, Molossus molossus, Tadarida brasiliensis, Noctilio leporinus, and our field research reported documents an additional three species of bats from the island for the first time--Monophyllus plethodon, Ardops nichollsi, and Natalus stramineus. Re-examination of the single voucher of Myotis nigricans nesopolus has led us to exclude this species from the fauna of Saint Martin/Sint Maarten. We discuss possible causes of these decreased population levels and we express some concerns about the future conservation status of the chiropteran fauna of the island.

SBH-ST. Barts

Species (5): Five species of bats are known from Anguilla—Monophyllus plethodon, Brachyphylla cavernarum, Artibeus jamaicensis, Molossus molossus, and Tadarida brasiliensis. Saint Barthélemy does have a number of important caves that can be used as roosts by four of the five species on the island (Molossus molossus is the exception). It will be important as development of the island proceeds to protect these cave systems.
